Prediction markets challenging tribal casinos’ hard-won place in U.S. gambling
Summary
Prediction markets, platforms like Polymarket and Kalshi where users wager on event outcomes, are challenging the dominance of tribal casinos in the U.S. gambling landscape. Tribal leaders express concern that these markets are circumventing regulations established by the Indian Gaming Regulatory Act (IGRA) of 1988, which was a compromise allowing tribes to develop casinos as a means of economic self-determination. Tribal casinos generate over $40 billion annually, funding vital social services. The Indian Gaming Association is advocating for congressional action and building a legal defense fund, arguing prediction markets constitute unlawful gambling. Kalshi, Polymarket, and Robinhood maintain they are operating futures trading platforms, not gambling operations, and are facing lawsuits from states and tribes. The outcome of these legal battles and potential legislative changes will determine the future of both industries and the financial stability of Native American communities.
